Question

【題目】 “Mosquitoes are more likely to bite people with type O blood (O型血).” Have you heard someone say this before? It’s not true!

I’m not very picky (挑剔的) about blood types. In fact, I cannot tell which blood type you are. Only doctors can do that.So how do I choose who to bite?

I can smell the carbon dioxide (二氧化碳) on people’s breath. The more you breathe out, the more easily I can find you. This means larger and fatter people are more likely to get my “kiss”.

I can also find food by smelling. You play outside and start sweating (出汗) all over. I can smell the lactic acid (乳酸) in your sweat. So yummy!

I also use my eyes to find food. But my eyesight (視力) is not very good. If you are trying to avoid me, do not wear colors such as black, red or dark blue.

It’s only females who have a taste for blood. They need it for their eggs. Male mosquitoes do not bite. For a proud mosquito mother, not just any blood will do.

Answer 1

【答案】

【1】B

【2】C

【3】C

【4】B

【解析】

有些人說蚊子喜歡咬O型血的人，其實(shí)這是沒有科學(xué)依據(jù)的。這篇短文以一只蚊子的口吻，講述了蚊子到底喜歡咬什么樣的人。

【1】

細(xì)節(jié)理解題。根據(jù)短文第二段“In fact, I cannot tell which blood type you are. Only doctors can do that.”可知，蚊子并不知道人類的血型。故選B。

【2】

細(xì)節(jié)理解題。根據(jù)短文第四段“You play outside and start sweating (出汗) all over. I can smell the lactic acid (乳酸) in your sweat. So yummy!”可知，蚊子可以聞到人類汗液里面的乳酸，如果我們剛做完鍛煉，這時(shí)候容易出汗，更容易被蚊子咬。故選C。根據(jù)第五段“If you are trying to avoid me, do not wear colors such as black, red or dark blue.”可知A不對(duì)；根據(jù)第三段“This means larger and fatter people are more likely to get my “kiss”.”可知B不對(duì)；D選項(xiàng)在文章中沒有提到。

【3】

推理判斷題。根據(jù)短文第二段“I’m not very picky (挑剔的) about blood types.”可知，蚊子對(duì)血型并不挑剔，它什么血型的人都咬。C選項(xiàng)符合文意，故選C。

【4】

細(xì)節(jié)理解題。根據(jù)文意可知，短文第三、四、五三段介紹了蚊子喜歡咬什么樣的人；從第四段中我們可以知道蚊子能聞到什么，因此c和d是對(duì)的，選B。
